ACCOUNT-FINDING MACHINE.

Application tiledl November 8, 1920. Serial No. 422,658.

This invention relates to machines for finding accounts. i

In the account finding machine described in applications Serial Number 229,996, filed April 22, `1918, and Serial Number 352,601, led January 19, 1920, now Patent No. 1,615,806 of J an. 25, 1927, and also in British PatentiNo. 153,344, November 2, 41920, the account cards arearranged in a tray (or a series of trays) and a desired account is foundby primary location of a group of cards,v secondary location of a-division or unit of cards, and avtertiary location of a card, and the finally located card is "then isolated. This is accomplished by providing selecting mechanism which is set by selective jmanipulative Vmeans comprising a series ,of keys so as to effect such selection.

After a desired account or accounts has or havey beenfound and isolated by such location and elevation ofthe selectors, the selecting mechanism is restored to clear the machine by operation of a crank. This, however, requires the manual operation of the crank after each account hasbeen found. Accordingly, where a series of cards in a tray are desired successively, an undue amount of labor is required for the successive clearings of the machine. f

One of the objects of this invention, therefore, is to provide a machine whereby the selecting means will be automatically restored and more particularly whereby the restoring of theselecting means is accomplshed upon and after an interval following the setting of the selecting means.

In order to audit thel accounts," auditing mechanism is employed as distinguished from the normal selecting mechanism, which is arranged to locate and isolate a. series of cards, one in each unit, so as to not only check 1p the system, but also find lost or misplaced accounts. It is desirable, however, when auditing, to render the automatic restoring yof the selecting means ineffective, especially since during auditing a series of cards, one hundred `in number, is isolated by auxiliary isolating means which is manually operated and, therefore, manually restored. Another object of this invention, therefore, is to provide means for rendering the automatic restoring of the selecting means ineffective when desired, and more especially during auditing of the accounts.

Further objects will appear from the detail description taken in connection with the accompanying drawings, in which:

Figure 1 is a detail side elevation of so much of the mechanism of the account nd 00 ing machine ofthe application referred to as is pertinent to this invention;

Figure 2 is a` detail front elevation, showing the automatic restoring mechanism embodying this invention; 55

Figure 5 is a .plan of Figure 4;

Figure 6 is a detail view taken about on line 6 6, Figure 2; and 70 Figure 7 is a detail, somewhat reduced,

showm. the motor connection.

In t el diierent views, parts have been omitted; this has been done to promote clearness, for ifall the parts particularly relevanvwere shown, it would obscure the particular mechanism under consideration.

Referring more particularly to Fi re 1 which shows so much of the mechanlsm o the machine described and shown in the application referred to as will render its operation clear, 1 designates the base of the machine which is provided with suitable side members 2 and brackets 3 and 4 so as to provide a frame for the mechanism. A carlll ports shafts 9 provided with clutches 10 for selectively clutching the shafts to a desired pair of selectors S. It will be understood that springs are provided for moving all of the parts.

Mounted above the selectors is a tray 11 having partitions 12 dividing the tray into a series of compartments, each of which is arran ed to receive a series of ten cards C provi' ed with variant tabs along their lower edges corresponding respectively to the positions of the cards in a compartment.

A series of normal keys 13 lare provided, these being ten in number, and as there are three locations in order to finally locate a desired card, a shiftablc transmitter carrier 14 is provided to transmit the movements of the keys to the mechanisms for controlling the primary, secondary and tertiary operations of the selectors. The primary or group selection of the selectors is obtained by clutching a pair of selectors with the shafts 9 and for this purpose, the plungers 15 in the transmitter carrier are arranged to cooperate with a series of latches 16 which normally retain the levers 17 connected by links and arms with and for operating the clutches 10. The secondary location is obtained by shifting the carrier 7 rearwardly the required number of spaces which is aecomplished by a series of stops 18 cooperating with a cross-bar 19 on the carrier and controlled by latches 20 from the keys 13 through the plungers 15. The tertiary location is obtained by moving the side members of the carriage 5 inwardly, this being accomplished by the release of a latch 21 cooperating with a cross bar 22 connected with the carriage and cooperating with a series of variable sto s 23 controlled by a series of elements 24 rom the keys 13 operating through the medium of the plungers.

After final location, the shafts 9 are rotated upon release of the latches 25 and 26 cooperating with a lug 27 on a link 28 connected with these shafts in the manner shown in said Patent No. 1,615,806.

For instance, in order to obtain card #.122, as shown in `Figure 1, the auditor will depress successively keys 1, 2 and 2. Upon the primary depression of the l key, the 1 selectors S will be clutched with the shafts 9; upon secondary depression of the 2 key, the carrier 5 will be moved forward and located in position to aline the l selectors S with the 20 compartment; upon tertiary depression of the 2 key, the selectors will be moved inwardly to aline the 1 selectors in the,20 compartment with the tabs on the 2 card. Upon rotation of the shafts 9, the 2 card will now be elevated.

In order to restore the mechanism to normal positionthe following mechanism is provided. The link 28 is connected with a bell-crank lever 29 having a roll 30 cooperating with a cani 31 connected by a link 32 with an arm 33 on a rock shaft 34 provided with an arm 35 connected by a link 36 with an arm i7 of a bell crank lever loose on a rock shaft 38, the other arm 57 being connected with the cross head 19, as shown in latent No. 1,615,806. Segments ,58 and 59 fixed to the ends of the shafts 38 and 39 mesh and connect these shafts, and shaft 38 is provided with acrank 39. An arm 4() is also fixed to the rock shaft 34 and is connected by a link 41 with the bar 22. There are similar connections to the other mechanisnis, the result being that upon moving the crank 39 in the direction of the arrow, Figure 1, the parts will be restored to normal position with the selectors in normal or (V" position.

rIhe audit selectors I are arranged to be interconnected with the normal selectors S by a shift bar 42 operated by the audit key 89 as shown in Patent N0. 1,615,806 and manually operative means are provided for then raising all of the selectors. For this purpose, the rock shaft 38 has loosely mounted thereon an arm 43 connected by a link 44 with a lever 45 arranged to take behind the pin connectingl the link 28 with the bellcrank lever 29. Accordingly, upon tripping of the latches 25 and 26, the selectors may he raised manually by moving the arm 43 in the direction of the arrow, Figure 1.

As described in the applications referred to, the depression of keys will release the different mechanisms so that under the action of the springs, the primary, secondary and tertiary locations will be rendered. A motor is, however, provided for restoring the mechanisms, (see application Serial Number 229.996) this motor being attached to the base 1 and its shaft being shown at 46 and a clutch is provided between the motor and the rock shaft 38, which clutch has an element 47 having a helical outer periphery including a shoulder 47a engaged by a stop 48 connected to a lever 49 pivoted at 50 on the base and connected by a link 51 with an arm 52 on a shaft 53 having an arm 530 connected in turn by a lever 54 with a tripping liar 55, a spring 56 being provided for normally holding the stop 48 down. The shoulder 47a corresponds to the pin 404 in application Serial No. 229,996, and British Patent No. 153,344 and serves substantially the same purpose. Accordingly u on depression of the tripping bar 55, re ease of the shoulder 47L and element 47 will cause the motor to be clutched to the actuating rock shaft 38 so as to restore the mechanism.

It is to be understood that where such motor mechanism is provided, the crank 39 can be omitted.

The mechanism so far described is fully described in the disclosures referred to and further description is, therefore, unnecessary, it being noted that the motor which is normally in motion will, upon actuation of the tripping bar or upon inovement'of the lever 49, be connected with the actuating rock shaft 38 so as to clear the machine.

It will be noted that after filial location of the selecting mechanism and upon tripping of the latches 25 and 26 causing release and therefore actuation of the shafts 9 to elevate the located selecting mechanism, the bellcrank lever 29 is moved about its pivot so as to cause the lever arm thereof and the cam roll 30 on this lever arm to be elevated.

Referring now to Figures 2 to 5 inclusive, slidably mounted on the bracket 3 is a shifting bar 60 having a cam portion 61 cooperating with a cam roll 62 on the pin connecting the stop 48 and the lever 49. This bar is slotted at 63 and the slot is engaged by a stud 64 on a cross-head 65 provided with a stud 66 moving in a guide slot 67 in a bracket 68 mounted on the base. This cross-head is connected with a spring 69 anchored on the base. The cross-head is provided with a beveled lug 70 in the path of the toe 71 on an arm. 72 pivoted on a bracket 73 attached to the bracket 3 and having the free end 74 thereof in the path of the cam roll 30 on the bell-crank lever 29. A spring 75 connects the arm 72 with the bracket 3 and normally tends to hold this arm down against a stop 760 on the bracket 73.

Upon elevation of the located selectors, when the bell crank lever 29 is moved by the cam 31 (during operation of the resetting lever 39), the cam roll 30 will strike against the free end of the arm 72 and move the toe` 71 thereof out of the path of the lug 70 thereby permitting the spring 69 to move the bar 60 forward and cause the cam 61 thereon by engagement with the roll 62 to elevate the stop 48 so as to release the clutch and permit themotor to restore the mechanisms and clear the machine. Accordingly upon final location and isolation of a card, the selecting mechanism will be automatically restored.V

Now it is desirable that there be a time interval between the isolation of a card and the restoring of the mechanism in order to permit the card to be examined and in order to insure that all parts will be finally located. In accordance with this invention, therefore, retarding means is provided so as to provide an interval following such setting of the selecting mechanism, after which thc selecting mechanism is restored. Accordingly, the cross-head 65'has attached thereto the stem 76 of a plunger 77 working in a cylinder 78 pivoted in a bracket 79 on the base so as to form a dash pot. This dash pot is, however, provided at its side with a port 8O open to the air and arranged to be uncovered movement.

by the plunger. A regulatin valve 81 may further be provided to initia ly regulate an aperture in the end of the cylinder.

Upon release of the cross-head, the movement thereof will be retarded by the reduction of pressure below atmosphericV pressure in the dash pot cylinder and the resultant retarding efl'ect of the external atmospheric pressure. This retardation will continue until the plunger 77 asses the port 80 at which time atmospheric pressure will be reestablishcd inside of the dash pot. Accord ingly, the first movement of the cross head will be a slow one succeeded by a quick The slow movement is for the purpose of providing a time interval after the setting of the selecting mechanism, while the quick movement serves to release the clutch and permit the motor to restore the selecting mechanism. This interval may be varied by adjustment of the valve 81 so as to suit requirements.

When auditing, it is desirable that the automatic restoring mechanism be rendered inell'ective, for at this time, the period of inspection is unusually long. Accordingly, mechanism is provided for this purpose. The clutch-shifting bar 60 has a lug 82 arranged to be engaged by a latch 83 pivoted at 84 on the bracket 3 and having an arm 85 provided with a face 86 cooperating with a pin 87 on a bar 88 connected with the audit key 89. A spring 90 connected with the arm 85 and anchored on the bracket 3 tends to hold the face 86 against the pin 87 and this arm is also provided with a recess 91. Upon de I'ession of the audit key 89, the pin 87 wil move down along the faceV 86 until it drops into the recess 91 whereupon the spring 90 will swing the latch 83 and cause it to take behind the lug 82 on the shifting bar 60 so as to prevent clutching of the clutch when the selectors are raised for auditing purposes. Accordingly, during auditin ,the automatic restoring mechanism is ren ered ineffective. The mechanism, however, is restored upon de ression of the tripping bar 55 and according y in order to again restore the automatic mechanism, the link 51 is connected with a lever 92 pivoted on the bracket 3 and provided with a pin 93 adapted to engage the arm 85 and shift this arm back so as to r'aise the latch and release the bar 60 and also to permit the audit bar to be again raised by its spring.

lVhen the mechanismds restored by the motor, the automatic mechanism is also restored. For this purpose, the arm 40 has a pin and slot connection with a link 94 pivoted on the stud 64. Accordingly, when the arm 40 swings to the left, Figure 4, in clearing the machine, it will, after a` limited movement (sufficient to take up the lost motion between the cross head and the link 94) return the cross head to normal posiance with this invention, upon setting the' normal selectors to locate and isolate a card, the mechanism will after final location and isolation be restored for subsequent operation. The provision of the retarding mechanism, however, causes a time interval after such final location and isolation so as to permit inspection and complete action before the mechanism is restored. Accordingly it is not necessary for the auditor to depress the tripping bar after the location of each card. When auditing, however. the automatic mechanism is rendered ineffective, but this mechanism is again rendered effective after the machine has been restored through the medium of the tripping bar or any other means.

In the specification and the claims, the term card is used in its broadest sense so as to cover ordinary loose leaves, cards, sheets and other accounting elements.
